Problems solved by technology

Although the fuel nozzle of the '145 patent may improve air / fuel mixing and flame distribution, it may be insufficient and problematic.
It is also possible for the fuel collected on the barrel to coke and create obstructions or blockages that reduce functionality of the fuel nozzle.
In addition, this improper distribution and combustion of the liquid fuel could reduce operational efficiency of the turbine engine.

Embodiment Construction

[0013]FIG. 1 illustrates an exemplary turbine engine 10. Turbine engine 10 may be associated with a stationary or mobile work machine configured to accomplish a predetermined task. For example, turbine engine 10 may embody the primary power source of a generator set that produces an electrical power output or of a pumping mechanism that performs a fluid pumping operation. Turbine engine 10 may alternatively embody the prime mover of an earth-moving machine, a passenger vehicle, a marine vessel, or any other mobile machine known in the art. Turbine engine 10 may include a compressor section 12, a combustor section 14, a turbine section 16, and an exhaust section 18.

[0014]Compressor section 12 may include components rotatable to compress inlet air. Specifically, compressor section 12 may include a series of rotatable compressor blades 22 fixedly connected about a central shaft 24. As central shaft 24 is rotated, compressor blades 22 may draw air into turbine engine 10 and pressurize t...

Abstract

A fuel nozzle for a turbine engine is disclosed. The fuel nozzle has a common axis, a body portion disposed about the common axis, a barrel portion located radially outward from the body portion. The fuel nozzle also has at least one swirler vane disposed between the body portion and the barrel portion and a liquid fuel jet disposed within the at least one swirler vane. The at least one swirler vane is configured to radially redirect an axial flow of air. The liquid fuel jet is configured to inject liquid fuel in a radial direction relative to the common axis.

Description

TECHNICAL FIELD[0001]The present disclosure relates generally to a fuel nozzle of a turbine engine, and more particularly, to a fuel nozzle having a swirler-integrated radial fuel jet.BACKGROUND[0002]Internal combustion engines, including diesel engines, gaseous-fueled engines, and other engines known in the art, may exhaust a complex mixture of air pollutants. The air pollutants may be composed of gaseous compounds, which may include nitrous oxides (NOx). Due to increased attention on the environment, exhaust emission standards have become more stringent, and the amount of NOx emitted to the atmosphere from an engine may be regulated depending on the type of engine, size of engine, and / or class of engine.[0003]One method that has been implemented by turbine engine manufacturers to comply with the regulation of these emissions while maintaining high engine efficiency has been to design and produce turbine engines that generate an evenly distributed flame having a low flame temperatu...
